and then I didn't find this family again.
I thought Jessee died after Alda was born but then I found the following.
Janie Bright Barefoot
Born: 1914, Dismal, Sampson, NC
F: Jesse B. Barefoot
Source: NC Birth Index 1800-20000
I'd contact the Sampson County Historical Society, www.sampsonhistory.org/
and ask if they have a local death index, indexed newspaper death notices and inventoried cemeteries. They might be able to find info about Jessee's death.
After you find his death date, you can look for his probate records if you desire.
Also the North Carolina State Archives has marriages 1741-1868. They can tell you when Nancy married Robert Jernigan which should help too. Successful Searching!
